ASME Section V: T-276 IQI SELECTION
T-276.2 Size. The designated hole IQI or essential wire shall be as specified in Table T-276. A thinner or thicker hole-type IQI may be substituted for any section thickness listed in Table T-276, provided an equivalent IQI sensitivity is maintained. See T-283.2.
(a) Welds With Reinforcements. The thickness on which the IQI is based is the nominal single-wall material thickness plus the actual weld reinforcement thickness estimated to be present on both sides of the weld (I.D. and O.D.) . The values used for the estimated weld reinforcement thicknesses shall not exceed the maximums permitted by the re fe rencing Code Section. Physical measurement of the actual weld reinforcements is not required. Backing rings or strips shall not be considered as part of the thickness in IQI selection.
(b) Welds Without Reinforcements. The thickness on which the IQI is based is the nominal single-wall material thickness. Backing rings or strips shall not be considered as part of the thickness in IQI selection.
(c) Actual Values. With regard to (a) and (b) above, when the actual material/weld thickness is measured, IQI selection may be based on these known values.
